Or like in my case, where my motor was a 13B to start with, not a 13BT.

how do i test compression with the engine out of the car and the transmission still in the car?
Also, I'm asking again, what should i check to be somewhat secure that the engine will work in the car?
(check inside oil pan...., check apex seals through exhaust ports....)
I need to know because i start work on the thing friday morning.

I'd check the apex seals through the exhaust ports, then just turn it by hand and make sure all the 'tough to turn' (making compression) spots occur evenly throughout the rotation.

Even still, many of them have sat for long periods eventually causing deposits to stick the apex seals causing inadequete seal for a good compression. This is one of the reasons ATF is used...to breakdown the carbon deposits and free the sticky apex seals. So even though the compression is low it can be just a stuck apex seal that needs a little lube and spun around a few times more...
